- Abstract
A CdS embedded metal-organic framework (MIL-100) composite was synthesized and used for photocatalytic degradation of nitrite ions. The obtained samples were characterized by a series of techniques such as X-ray diffraction (XRD), N adsorption/desorption, transmission electron microscopy (TEM) and UV-Vis diffuse reflectance spectra (DRS). The results show that CdS nanoparticles were dispread and embedded on the MIL-100 crystals. The CdS/MIL-100 composites exhibited significant activities for photocatalytic degradation of nitrite ions through a disproportionation process in a neutral aqueous solution without any sacrificial reagents. When 20 wt% of CdS was embedded, the highest degradation yield of 92 % was achieved in 10-ppm NaNO aqueous solution under simulated solar light irradiation, which was fivefold of bare CdS. The enhancement in photocatalytic activities could be contributed to photosensitization and supporting of metal-organic framework scaffold.
